Where the pic or question?
4x = 76
Where x is how many awnsers he got correct and 4 how many points each correct question awnsered.
Now you just have to isolate x by dividing both sides of the equation by 4
4x/4 = 76/4
x = 19
So he got 19 questions right and 10 awnsers wrong. In total there were 29 questions on his test
Answer:
The probability is 1/41664.
To calculate the probability, write a fraction. The numerator is the number of ways the outcome can occur. The denominator is the number of different outcomes.
Thus, 1 is the number of outcomes we want. 41664 is the total number of different combinations possible.
